These keyboards dont seem to allow the records to be initialized, and hence a timeout occurs when the usbhid driver attempts to initialize them. The patch just adds the signature for these keyboards to the hid-quirks list with the setting HID_QUIRK_NO_INIT_REPORTS. This removes the 5-10 second wait for the timeout to occur.
